The supernatural world of American Horror Story: Coven just got a little more crowded: EW has learned that Fringe’s Lance Reddick will be joining the FX show as Papa Legba when the horror anthology returns in January. The character, described as Coven’s version of “voodoo Satan,” plays a pivotal role in the life of Marie Laveau (Angela Bassett) and will be an important figure in the series’ remaining four episodes. Show co-creator Ryan Murphy teased Legba’s involvement in our recent EW AHS: Coven cover story: “You find out that’s how come Marie Laveau looks so good – because she sold her soul!”
